Intrahepatic bile duct stones 4 x 3 millimeters are not able to be expelled. Intrahepatic bile duct stones are not different from urinary stones Intrahepatic bile duct stones are usually not expelled on their own, and urinary stones can be expelled from the body with urine, especially smaller urinary stones, which may be cured. Intrahepatic bile duct stones, even if they are relatively small, can get stuck in the common bile duct when they are excreted and even lead to pancreatic inflammation, which is different from urinary stones. As long as intrahepatic bile duct stones do not lead to atrophy of the liver and do not form cancer of the bile ducts, they generally do not require special treatment. Intrahepatic bile duct stones excreted into the common bile duct and jammed in the pancreatic ducts may lead to obstructive septic bile duct inflammation and acute pancreatitis, which can lead to more serious problems. When intrahepatic bile duct stones are detected, it is recommended to consult the Department of Hepatobiliary Surgery of a regular hospital.
